Four official federal government reports provide the full details of the tragic SL-1 prototype nuclear power plant accident of January 3, 1961, the first and only immediately fatal American reactor accident. Three servicemen were killed in the incident at Idaho National Laboratory (INL). Major documents in this ebook compilation include the SL-1 Reactor Accident Interim Report, the IDO (Idaho Operations) Report on the Nuclear Incident at the SL-1 Reactor, SL-1 Recovery Operations, and the Final Report of SL-1 Recovery Operation. Other document excerpts provide background information on the reactor and the accident, and NASA'S assessment of the accident and its applicability to spaceflight safety. The SL-1 power plant (originally designated ALPR), prototype for a remote arctic installation, was designed, constructed and initially operated by Argonne National Laboratory. It is located at the National Reactor Testing Station near Idaho Falls, Idaho. Combustion Engineering was selected as operating contractor for this plant on the basis of their response to an Atomic Energy Commission invitation issued in June, 1958 and assumed operating responsibility on February 5, 1959. After nearly two years of operation a nuclear excursion occurred on the night of January 3, 1961, when a military crew of three men were assembling the reactor control rod drive mechanisms. The resulting blast killed the three crew members, produced extensive damage inside the reactor vessel and secondary damage to the reactor room by ejected missiles. The mechanical and material evidence, combined with the nuclear and chemical evidence, forced investigators to believe that the central control rod had been withdrawn very rapidly. They built a mock-up of the reactor vessel with identically sheathed and weighted control rods. In King Arthur fashion, men of lesser, similar, and greater strength as the crew tried to lift the rod. Most managed with little difficulty. The scientists questioned the cadremen: "Did you know that the reactor would go critical if the central control rod were removed?" Answer: "Of course! We often talked about what we would do if we were at a radar station and the Russians came. We'd yank it out."

U.S. Atomic Energy Commission (Idaho Operations Office) briefing about the SL-1 Nuclear Reactor Meltdown. The SL-1, or Stationary Low-Power Reactor Number One, was a United States Army experimental nuclear power reactor which underwent a steam explosion and meltdown on January 3, 1961, killing its three operators. The direct cause was the improper withdrawal of the central control rod, responsible for absorbing neutrons in the reactor core. The event is the only known fatal reactor accident in the United States. The accident released about 80 curies (3.0 TBq) of Iodine-131, which was not considered significant due to its location in a remote desert of Idaho. About 1,100 curies (41 TBq) of fission products were released into the atmosphere. The facility, located at the National Reactor Testing Station approximately 40 miles (64 km) west of Idaho Falls, Idaho, was part of the Army Nuclear Power Program and was known as the Argonne Low Power Reactor (ALPR) during its design and build phase. It was intended to provide electrical power and heat for small, remote military facilities, such as radar sites near the Arctic Circle, and those in the DEW Line. The design power was 3 MW (thermal). Operating power was 200 kW electrical and 400 kW thermal for space heating. In the accident, the core power level reached nearly 20 GW in just four milliseconds, precipitating the reactor accident and steam explosion.

The little-known true story of a mysterious nuclear reactor disaster—years before Three Mile Island, Chernobyl, or Fukushima. Before the Three Mile Island incident or the Chernobyl disaster, the world’s first nuclear reactor meltdown to claim lives happened on US soil. Chronicled here for the first time is the strange tale of SL-1, an experimental military reactor located in Idaho’s Lost River Desert that exploded on the night of January 3, 1961, killing the three crewmembers on duty. Through exclusive interviews with the victims’ families and friends, firsthand accounts from rescue workers and nuclear industry insiders, and extensive research into official documents, journalist William McKeown probes the many questions surrounding this devastating blast that have gone unanswered for decades. From reports of faulty design and mismanagement to incompetent personnel and even rumors of sabotage after a failed love affair, these plausible explanations raise startling new questions about whether the truth was deliberately suppressed to protect the nuclear energy industry.

In May, 1961, it waa determined no renewed nuclear reaction in the SL-1 pressure vessel was possible as long as water was excluded. It was therefore possible to proceed with the final phase of the SL-1 recovery. This work consisted of moving the pressure vessel and core to the Hot Shop at the north end of the National Reactor Testing Station, dissecting and analyzing the reactor and its components, cutting up and burying the reactor building, and decontaminating the rest of the SL-1 area. These things were accomplished by the General Electric Company between May 1961 and July 1962. It was determined that the central control rod was bound in its shroud at a position corresponding to 20- inch withdrawal. Analysis of the pertinent data showed that the amount of reactivity associated with this rod position, inserted at a rate compatihie with manual withdrawal of the rod, can explain the significant evidence which was coliected. No other means of withdrawing the rod was found to be in accordance with the evidence. It was found that the relatively low yield (130 Mw-sec) nuclear excursion produced a water hammer with pressures up to 10,000 psi, which, in turn, caused the pressure vessel to rise some 9 feet in the air.

A summary of activities which took place following an incident at the SL- 1 is presented. No attempt to determine the incident cause is included. A brief description of the SL-1 and the operating program in progress prior to the incident is given along with detailed information on various aspects of the past incident developments. (J.R.D.).
